internally threaded ring or collar isv threaded on this collar 19e to assist in maintaining the halves of the casing in assembled position.v A barrel or ltube is threaded into a portion of the collar 22 and in turn is provided withv a cap 28, said ca being threaded thereon. A stud 23b proJects inwardly from cap 23?, the latter furnishing a seat for a coiled spring 24. A stud or boss 2Od extends from one endiofthe block 2O and a collar 20e' is mounted thereon, the latter being provided with a base flange 2Of against which the other end of the spring 24 contacts' when in the position shown, for example, in Fig. 3.l The block 20 is constructed with a trapezoidal contour having the inclined side walls 20g, as clearly shown in Fig. 10, for

example. 'I further provide lwhat I term levers 25, each of these levers being provided -with a rectangular portion 25, see Fig. 8, closely fitting in slots 18e of bosses 18c on arms 18. These levers '25 also have the bosses 25 projecting outwardly from each side .ofthe rectangular portion 25a and fitting in,k the apertures 18d of component arm members .IS, these bosses and thev rectangular portion' 25 'l'ieingprovided with a through extending bore or aperture 25. At one-end the levers 25 are provided with the heady orenlarged portion 25cl slotted, as indicated `at 25e, t0 provide side flanges. A circularaperture 25f is provided in each of the side flanges 25?. In these apertures 25 4aremounted the contact blocks 26, as I term them, the same being cylindrical in shape provided `with the slots 26El forming'tside flanges 26., The relation and arrangement of these levers25 is such that when assembled, the 4side flanges 25e of contact blocks 26 will fit over the side walls of the block 20 the flattened portion of the contact blocks 26 being adapted to ride on the side walls.

the cylindrical shape of said blocks being such as to permit its rotation relative to the levers 25, for ,a purpose to be hereinafter described.

` It will be apparent that when the device is assembled, should the ends of the arms 18 be brought together from position shown in Figs. 2 and 3, they will pivot about their mounting in circular apertures 1f)n causing the levers-25 to partially rotate about a commoncenter with them. This will tend to remove the contact blocks 26 from contactwith the plate 20, but the action of the coiled -spring 2-l is such as to maintain the plate or block 2() in constant engagement with the contact blocks 26 when such movement occurs. lVhen a reverse or spreading movement of the arms 1S takes pace, it' will be apparent that the contact blocks 26 will place, as will also be apparent.

'of the force exerted thereon will be resolved along the longitudinal 'axis of the block 20, as will be apparent, and a great resistance is afforded to such spreading movement of the arms 18. At the same time the block 20 being symmetrically constructed, no binding thereof with respect to the casing will take rl`hose skilled in the art will understand that by varying the inclination of the sides of the block 20 relative to the longitudinal axis, the amount of resistance afforded -by the block 20 to the spreading movement of tpe arms may be varied; also the resistance f the spring 2l to movement of the block 20, such as to compress it, will increase the resistance afforded to the spreading movement of the arms. It will be apparent, therefore, that I have provided a construction which will permit free movementI of the arms 18 toward each other, but will greatly resist the spreading movement of such arms, the amount of this resistance being capable of variation according to thc inclination of the sides of the block 2() and the strength of the sp1-ino 24. In applying my device to a ve hicle, such as that. shown in l"ig. 1, for example, I arrange the absorber between thel body and the. axle of the vvehicle so that movement of the former toward the latter will not be effected, save by the action of the usual vehicle springs 1T. -When the body tends to move away from the axle in reactionto'the above described movement, however, the resisting effect of the absorber is felt and there is no tendency of tht-.vehicle t0 vibrate or move up and down beyond the normal or rest position thereof. In attaching my improvement to a vchichI l provide the attaching member Si() .comprising a head 30 adapted to tit over ,one flange l5" of channel frame member l5" being retained in position b'v the set screw 30". lstud 30 projects outwardly from the head 30 and is thereof upwardly and insert a set screw 30'* therethrough,with the head bearing against the web of Vthe channel l5, as is clearly shown inV Fig. 1l. The operationeof attaching and screwing this fastening member in place is believed to be obvious to those skilled in the art. For the other arm I8 of the shock absorber, I provide an attaching member 3l having the split ring portion 31 -adapted to fitaround the axle casing 16,

being clamped thereto by the bolt and nut n arm projects upwaitll.

. from and is-apertured. at 31 vto permit 'atltachment ,of .the end of one .of the armsIS,

as shown 1n. F--ig..l. I have, shown ,thefends of the two arms y1821s relatively otlset-with respect` tov the-vertical in lthe attachment shown in F ig. l, this oii'setting arrangement being advantageous in certain instances to4 minimize the initial'shock or stress applied to the plate or block 20 when first encounteringa bump or the like.

It yis obvious that modications are necesi sary in att-aching my device to various constructions of vehicles or the like and that springs of different tension may be utilizedand also that the inclination of the sides of the block may be varied to vary the resistance afforded by my device.

It will also be apparent that many other modifications and changes are possible, and I do not wish to be restricted tothe Jform shown and` described beyond the scope ot the rappended claims.
